Configuring Switches Shared by the Front and Back Ends

Configuring Switches Shared by the Front and Back Ends

This section describes how to configure switches in a network
where the front and back ends share a switch.

Context

The following example
uses three storage nodes, two CE6800 series switches, and one CE5800
series switch to explain how to configure switches. Figure 4-2 shows the network planning.

Table 4-2 shows switch planning examples.
The planning values are only for your reference and are italic texts
in commands. You can replace them based on site requirements.

Name

Example

Switch shared by the front and back ends

Front-end VLAN: 100

service ports: 1/0/17 to 1/0/19,
2/0/17 to 2/0/19

Back-end VLAN: 2

storage ports: 1/0/1
to 1/0/3, 2/0/1 to 2/0/3

Uplink ports: 1/0/33 to 1/0/35, 2/0/33
to 2/0/35

40GE stack ports: 1/0/1 to 1/0/2, 2/0/1 to 2/0/2

IPv4 address: 10.10.10.10/255.255.255.0

IPv6 address: feco:1::2
64

If the switch version is another one, see the corresponding
document to complete the configuration. To obtain switch-relevant
documents, go to:

Procedure

Log in to a switch, query its version, and
configure the stacking status for two switches.

For details about how to log in to a switch, view its version,
and configure stacking, see Check switch versions and Set switches CE6800-1 and CE6800-2 to the stack state in chapter Configuring Switches > Configuring Switches on a 10GE Network > Networking for Switches Not Shared by the Front and Back Ends > Configuring Back-End Storage Network Switches.

Configure the PFC function for ports
of the switch on the back-end storage network.

NOTE:

The VLAN ID of the back-end network ranges
from 2 to 9. The recommended value is 2, which keeps consistent with
the default value of the virtual network port of a storage node. If
the value cannot be set to 2, change the ID of the virtual network
port on the storage node. For details about how to change it, see Modifying the Virtual Network Port ID on Each Storage Node.

Configure an IP address for MEth0/0/0, configure
SNMP, and check SNMP operations. For details, see Configure
an IP address for port MEth0/0/0 and Configure
SNMP in chapter Configuring Switches > Configuring Switches on a 10GE Network > Networking for Switches Not Shared by the Front and Back Ends > Configuring Back-End Storage Network Switches.

Run the display current-configuration command and press Enter to check related
configurations one by one.

Configure a CE5800 switch.

The management switch of the 10GE network where the front-end
service network and back-end storage network do not share switches
is configured in the same way as that of the 10GE network where the
front-end service network and back-end storage network share switches.
For details, see chapter Configuring Switches > Configuring Switches on a 10GE Network > Networking for Switches Not Shared by the Front and Back Ends > Configuring a Management Network Switch.
